Okay so I have come into a problem that I do not understand.
The question is :
An Airplane is flying at 250km/h in a direction of 336 degrees. Find the westerly and the northerly components of its velocity.
The issue that I am coming up with is when I draw a right triangle for this equation I do not know how to come up with Angle A
The answer for Angle A is 66 degrees but I have no idea how they come up with that
Thanks in advance
